Select the List Attributes tab.

List attributes are Page Lists of data related to the entity that are persisted in tables other than the entity table. The Merge Entity feature will present a comparison display for each of the List Attributes configured on this tab. Click on +Add attribute and provide a label and a reference to a Data Page that will fetch the list items that are related to the entity. Optionally add parameters to the Data Page reference. Properties of the Person Entity can be incorporated into the Data Page reference.

Add references to properties (Property 1, Property 2) mapped from the Data Page to be visible in the comparison display for the list. Only two properties may be mapped in this way in the default user interface. In order to support more than two properties in the default display section for the specific class type must be customized using Dev Studio. For an example displaying third property see PegaPS-Data-Address . ListItemDetails.
